It's almost like finger prints. I thought that you were trying to trace the messages and set up a profile.<<<<<<<. I am probably not sophisticated enough about mail routing to do this. My intent was to track down the source of the error and delete the user and if possible use the information to track down future error messages. I would like to see your bounces because Rick Narads error message isn't identical to my error messages. Meanwhile I had another twenty or so last night. They all popped in just after midnight. I'm also interested in what you do to track the messages. I only know what Peter Weiss mentioned in his note yesterday. Thanks, Eleftheria
